How much luggage can I take on domestic flights in Thailand?

Baggage allowances depend on your carrier. Bangkok Airways includes 20kg of checked luggage and 7kg carry-on with every economy ticket. Low-cost carriers (Thai AirAsia, VietJet, Nok Air) include 7kg of carry-on baggage by default, with 15kg-20kg checked bags available for a small add-on fee during booking.

How do I transfer between Bangkok Suvarnabhumi (BKK) and Don Mueang (DMK)?

A free AOT shuttle bus runs daily between BKK (Door 3, Level 2) and DMK (Door 6, Terminal 1). You must present a valid same-day flight ticket departing from the destination airport. Journey time is 50-90 minutes depending on Bangkok expressway traffic, so allow at least 3.5 hours between flights.

Why are flights to Koh Samui (USM) more expensive than Phuket or Krabi?

Samui Airport (USM) is a privately built and operated boutique airport owned by Bangkok Airways. Due to runway constraints and preservation of island tranquility, slot capacity is limited. Bangkok Airways includes complimentary boutique lounge access (free snacks, barista coffee, juice, Wi-Fi) and 20kg checked baggage for all passengers.
